• Serendipity in Settings and Hydrologic Processes Helped People Survive Extreme Environments of the Sahara Desert

  Ancient human societies in the Sahara Desert thrived during extreme aridity thanks to natural geological and hydrological features that serendipitously functioned as efficient water-harvesting systems. Research on sandstone massifs like Tassili n’Ajjer, Tadrart Acacus, and Messak Settafet reveals how these settings amplified rainfall, concentrating runoff into perennial lakes and groundwater sources—effectively creating 'natural technologies' that sustained hunter-gatherers and pastoralists during the African Humid Period (AHP). The study demonstrates that structural geology and stream networks acted as accidental rainwater harvesting systems, while sandstone aquifers stored ephemeral surface water, shielding it from evaporation. These findings highlight how integrated landscape management can secure water resources in arid environments, offering lessons for modern sustainability. Additionally, the research links these ancient water systems to the later development of qanat technology by the Garamantian Empire.

• Shelters and bones: Site-specific archaeofaunal taphonomy for identifying formation processes in Saharan Holocene rock shelters

  A study of the Takarkori rock shelter in Libya's Tadrart Acacus massif reveals that natural processes such as weathering, salt encrustation, and gnawing have created varied preservation conditions for mammal bones across different stratigraphic and chronological layers. This variability challenges assumptions about uniform taphonomic processes in arid environments, emphasizing the need for fine-scale analysis to distinguish between natural and anthropogenic influences on faunal remains. The research employs macroscopic, microscopic, and SEM-EDX analyses to systematically document bone surface modifications, providing a framework to improve interpretations of archaeological contexts in hyper-arid regions.

• Di Lernia Savino, Gallinaro Marina (eds), Atlas of Tadrart Acacus Rock Art. A Unesco Wold Heritage Site in Southwestern Libya

  The Atlas of Tadrart Acacus Rock Art, a monumental three-volume work spanning nearly 1,000 pages, reveals the intricate and diverse rock art traditions of the Tadrart Acacus massif in southwestern Libya. This UNESCO World Heritage Site, characterized by its extensive sandstone formations reaching up to 1,100 meters in altitude, hosts one of the most significant concentrations of prehistoric and historic rock art in North Africa. The atlas synthesizes contributions from ten authors, integrating institutional, historical, and archaeological perspectives to contextualize over 2,500 documented rock art panels. Through detailed analyses of motifs, styles, and chronological sequences, the work sheds light on the cultural and social dynamics of past societies, spanning from the Paleolithic to medieval periods. The research approach combines field documentation with archival studies, offering a comprehensive framework for understanding the artistic and symbolic expressions embedded in this unique landscape.

• Spatial analyses of archaeobotanical record reveal site uses and activities at Early to Middle Holocene Takarkori (Libya, Central Sahara)

  A comprehensive spatial analysis of archaeobotanical remains at the Takarkori site, part of the UNESCO World Heritage Site Rock-Art Sites of Tadrart Acacus, reveals sophisticated human activities during the Early to Middle Holocene. The study demonstrates that plant resources were not only utilized for subsistence but also integrated into ritual and cultural practices, indicating a planned and diverse management strategy. Exceptional preservation of micro- and macrofossils across multiple occupation levels allowed researchers to reconstruct socio-economic and cultural dynamics with unprecedented detail. By correlating botanical remains with site furniture and material artifacts, the study provides new insights into how space was functionally organized within the site, contributing significantly to our understanding of Holocene environmental and cultural adaptations in the Central Sahara.

• Colonisation and consolidation

  A significant gap of tens of thousands of years separates the last Pleistocene occupation and the first Early Holocene colonisation in the Tadrart Acacus region, marking a true reoccupation of long-uninhabited hyperarid zones. The study identifies the first confirmed human presence in this area around 11,600 calBP, attributed to small, specialised hunter-gatherer groups with northern provenance. These Early Acacus groups exploited Barbary sheep and avoided intensive water-based food resources, contrasting with contemporary southern Saharan practices. The research combines lithic assemblage analysis, site organisation studies, and environmental data to reconstruct this colonisation event, highlighting the role of reactivated hydrographic systems in facilitating human movement during periods of environmental amelioration.

• Diversification and experimentation

  Late Acacus hunter-gatherers in the Tadrart Acacus region exhibited significant cultural diversification during the Early Holocene, marked by the emergence of pottery and increased use of grinding equipment. This period saw a shift toward a broader dietary spectrum, including terrestrial and aquatic foods, with evidence suggesting early experimentation in managing wild Barbary sheep and cultivating wild cereals. The material culture and settlement patterns indicate extensive inter-regional networks connecting the central Sahara to neighboring regions. Archaeobotanical records further support the exploitation of grassland grains, reflecting an adaptive response to the expanding grasslands. This study highlights a pivotal phase in Saharan prehistory characterized by technological innovation and complex subsistence strategies.

• Southwestern Libya and the central Sahara

  Recent advances in archaeological research have significantly enhanced our understanding of past cultural pathways in the Tadrart Acacus massif and surrounding regions of southwestern Libya. This central Saharan area, characterized by its unique physiographic units and dynamic climate history marked by Holocene wet-dry oscillations, has emerged as a pivotal site for studying Saharan hunter-gatherer cultures. Despite challenges posed by the Arab Spring, novel approaches have revealed critical insights into the region's complex environmental and cultural evolution. The study integrates current environmental features with paleoclimatic data to reconstruct past human adaptations in this equidistant zone between the Mediterranean and Sahel belts.
